On a humid afternoon in late February, while brass bands rehearse outside, Ramesh Abeywickrama sits at a long table with a bottle of water beside him, exactly where he has been told to keep it.

A year ago, his cardiologist told him to slow down. The job at KPMG, with its late nights and perpetual urgency, had to go. He took a couple of months off before returning to work, this time at a tech firm in Malabe, something steadier, more forgiving. But before he signed the offer letter, he made one request. Mid-February to mid-March would be different. He would need time off. Half days, at least. There were commitments he could not miss.

He was not negotiating for rest or family time. He was negotiating for the Royal-Thomian Cricket Encounter, a cricket tradition older than the republic.

For 146 years, boys from Royal College and S. Thomas' College in Colombo have met in the "Battle of the Blues". The longevity of the rivalry is impressive, but the fact that it never missed a year is something else entirely.

Class of 1985, Abeywickrama now serves as Co-Chairman of the Royal-Thomian Joint Match Organising Committee, one Royalist paired with one Thomian at the head of a structure that oversees more than fifty people across committees handling everything from security and protocol to sponsorship, ticketing and playing regulations.

As a student at Royal College, Abeywickrama never made it to the "Big Match" against the Thomians. "I was never good at playing cricket," he says wistfully, seated in the Royal College Union building, the official alumni body founded in 1891. "But I didn't want to be away from it. If I couldn't be on the field, I wanted to be somewhere around it."

So after he graduated, he found other ways to stay close. First as a volunteer, then as Co-Secretary, learning to navigate ministries and police divisions, before rising steadily to the top of the organising committee.

Now, as Co-Chairman, he measures the rivalry not by its age but by its endurance. That it did not stop during the civil war's most volatile years, when Colombo lived under a constant sense of threat. That it did not stop when a pandemic shut borders, sealed cities and silenced stadiums.

"It was a bubble before a bubble," he says of the years from 2007 to 2009, as Sri Lanka's decades-long civil war reached its final and most violent phase. "People know the SSC as this historic cricket ground. But those three years, we had anti-aircraft guns inside the premises. Metal gates everywhere. Armed personnel. You could see rifles. It wasn't just cricket."

Security was tightened further because the families of the President and Prime Minister were often in attendance at the Big Match. Spectators were ferried in buses arranged by the organisers, each one checked before anyone boarded. "A bomb can explode in the bus too, right?" Abeywickrama says. "So we had to think of everything."

The tents still went up along the boundary, more numerous than for most international fixtures at the SSC. The papare bands, which evolved from Portuguese-influenced street traditions and became synonymous with cricket in the country through the Royal-Thomian rivalry, still played. The three-day match still began on time.

A decade later, the disruption was quieter but more complete. COVID brought a different kind of silence.

In March 2020, even as schools and universities were being shut and England's cricket tour was cancelled, the Royal-Thomian match went ahead before the scale of the threat was fully understood. A Thomian pilot who attended the match was later identified as one of the country's earliest cases. "The test results came out only on the last day," Abeywickrama says. "The match was done."

The backlash, though, was immediate. Health authorities ordered those who had attended to quarantine. The following year's 142nd Battle of the Blues was postponed repeatedly before being played in October 2021, behind closed doors at the SSC. The 143rd encounter was pushed to July, another departure from its traditional mid-March slot.

Organising the match in bubbles for two consecutive years required extraordinary measures. "We had to prepare for every possibility," Abeywickrama says. "Each school readied two teams. If one positive case meant the first XI had to isolate, another would step in. The match still had to go on."

Royal was also in administrative transition at the time, without a permanent principal. S. Thomas' warden stepped in, working closely with the authorities to ensure the arrangements held and traditions continued.

"To be a chairman, you have to be a Royalist or a Thomian but there were no sides in that moment," Abeywickrama says. "Inside the committee, when we are responsible for the match, we are not thinking as Royalists or Thomians. We are thinking about the tradition. If one school is going through difficulty, the other has to step up. Rivalry cannot come before responsibility. That's how it survives."

The saying around the match is simple: there is no Royalist without a Thomian, and no Thomian without a Royalist. The contest defines them, but so does the dependence.

Outside the committee room, the differences -- or the "social animosity," as Abeywickrama calls it -- are easier to see. Royal College, a government-funded national school in Cinnamon Gardens, sends out nearly 800 boys each year and draws from across Colombo's social spectrum. S. Thomas', an Anglican private school in Mount Lavinia, graduates closer to 200. Its campus stretches to the shoreline, removed from the city's noise and has long been associated with a narrower, more exclusive network.

On Big Match weekend, that contrast becomes visible under canvas. Royal's student tent dwarfs its counterpart, simply because Royal has more boys. Alumni tents on both sides operate on donation and invitation. Liquor flows. Access is controlled. "We have undercover cops to ensure that students don't go into the Old Boys' tents and drink," Abeywickrama says.

But step outside the SSC and the lines begin to blur. Pethum Samira Adikaram, the tuk-tuk driver who ferried me between the two schools, spoke of them in practical terms. "If you go to those two schools, you will always find a job," he said, pausing before adding, almost as an afterthought, "You will never go hungry."

The rivalry may divide the tents in March but beyond the boundary rope, the alumni networks - which include many former Prime Ministers and Presidents - often converge into a single sphere of influence.

Inside the committee room, that convergence becomes practical. "When we deal with ministries or defence, Royal handles much of that," Abeywickrama says. "Government is more involved with Royal, so we are more in touch. Everyone works to their strengths."

The rivalry is loud, but the cooperation quiet and precise. Abeywickrama is wearing a shirt embroidered with the Royal-Thomian logo, the two colours held in careful balance. Even the smallest details are guarded. "Royal colours are blue and gold, Thomian colours are blue and black," he says, pointing to the crests on his shirt. "So on the ticket, the words 'Battle of the Blues' have to be in blue. We are very particular about that. We don't let sponsors dictate terms when it comes to that."

Less than two weeks remain before the 147th edition. Ranjan Madugalle, the former Sri Lanka captain, ICC match referee and, before all that, a Royalist, will serve as chief guest. As tradition dictates, it's always a former captain from one of the two schools.

Abeywickrama has come to the Royal College Union office to sign cheques, clear invoices and speak to vendors. "You are lucky to catch me," he tells me. His phone rings often. Someone needs confirmation on tickets, someone else wants clarity on tent allocations.

"March is a month of half-days and full attention," he jokes. "At heart, we just want a good game, keep the history going."

When the last tent is dismantled and the final banner folded away at the SSC, Abeywickrama will return to his office in Malabe. The emails will have accumulated and the spreadsheets will be waiting. The pulse will steady. But come next March, he will ask for time off again. Not for himself but for Royal-Thomian, the one thing his heart does not mind beating a little harder for.
